Getting all types that implement an interface

Using reflection, this is how we get all types that implement an interface with C# 3.0/.NET 3.5 with the least code, and minimizing iterations.

var type = typeof(IMyInterface);
var types = AppDomain.CurrentDomain.GetAssemblies()
    .SelectMany(s => s.GetTypes())
    .Where(p => type.IsAssignableFrom(p));

Basically, the least amount of iterations will always be:

loop assemblies  
 loop types  
  see if implemented.
